To all whom il may concrrri:

ie it known thm l, llirnmcr Bionic, :1 (-ilim'u ni` the United States, residing uLSherinan, in the r-ounty oi Grayson and Suite ol Texas, have invented reunio useful lniprovemenls in \\'ood(`.olumn Turning Lathes, ol which the followingv is n snoeihoution.

This invention relates to iinprm'enients in ineens for turning und timing mlonial wood eolumns. ond

l has or its object, mnongrT others, the produetion of :i

simple and effective device whif-h muy iso used for moving the carriage lengthwise ol the lathe lied, and for operating the Crossleed of same.

It has for it further object to provide the cross-slide l5 of carriage with a Cutter head that muy he swiveled and lorked in any desired position, thus bringing the Cutters for the difieront service required in oni-retire position Lo perform saune.

lt has for an object, further to so dispose the rollers 26 upon which the carriage runs and the operating ineeh :mism where they will be out of thee-'sy oi the dust and chips.

Still a further object is to decrease the irictional Contact, whereby the carriage can he inside to run easier.

Other objects and advantages of the invention will hereinafter appear, and 1he novel tentures thereof will be particularly pointed our iu the appended elaims.

The invention is clearly illustrated in the sworn 30 panying drawings, whifh, with the letters oi relerenee marked thereon, forni a part of this specification, and in which` Figure l is a slde View in section, token longitudinally through the carriage base, showing the lathe riage mounted in operative position upon s. cross-seeand Fig. 4 is si View showing the finished end of a Col umn. Fig. 5 is a, front elevation of the swinging head with the ends of the spindle shown in section,

Referring now to the details of the drawings by 1etter, A designates the wooden bed or shears of a inthe.

11S/to one end of which is seeured in the usual manner en ordinary lathe-head, and at tho opposite end en ordinary Tail-stock, as commonly used on wood turning;

lathes; neither of which is shown in the drawing.

Secured to outside of lathe shear, and extending along front side of lathe, is provided a wooden treel B, capped with a thin plate of iron B and spared a slight distance from the shear A by bioeiis B?Y To the outside of bark lathe-shear, and extending the length of saine is provided a V shaped metal track C carried by metal brackets C and additionally supported hy nieiul liur (l2: on these'- irulhs. l, und C, run rnliere whiili vnrry lhe lullni--mnriuge.

D is the huso ol thi.L earrings nmde prurtimilly T shaped hy providing the rcur end with luiernl extensions Uf, lieueuth whirh are owl-hanging aprons ll'`, in n'hieli are inouilted horixoninl shafts lil, mil-vying guide roller l", haring.; V shaped periplieries adopted to run ou the V truuk (l, and thus eorry the rei'u porion oi' vurriuue, lilxtendingr the lenelh of niet-ul har (ff und sefured lliereio is :in L or unghiron (7*. 'lhv downwardly projecting hooks U* secured to outer apron D2 poss alongr under projecting flange of the :ingle bur thus holding' the hack portion of Car ringe lo trunk C. Seeured near iront end of ein-ringehase D, on the under side thi-reni and preferably made integral therewith, is downwardly projeetiug lug D3, provided with sn riiuiwnrdly projecting pin (l on which is looselyr journsled roiler H adapted to run on the track B and by which the iront end of mirriage D is Carried.

Motion transmitted to the Carriage from s suitable leadserew, sproeket chain, or other equivalent de\` ico, whieh muy he driven in the usual manner hy a driving-shai't or other prime motor, and when the feeding device eonsists oi o lendserew I, as illustrated, it passes through :i downwardly projeetiug lug.,r l" at (ached to enrrizigehase D; the lug being bored and threaded longitudinally to receive the screw. ln piave oi the solid nut :is shown, one provided with means for opening and Closing,Y it can he einpioyed, which would enshle the carriage to he quieky drawn hack hy hand.

The oross-slide D4 is iitted in suitable guiding Ways D3 upon the top of the carriage base D, and carries a swinging or oseillating head I. around the hase oi which is prmided 2i eirculair recess J that fits si cireib iur raised portion .l2 formed on the top side of Crossslide Di, heing monthly held in this position by stud holt At the side of swinging head J is a projecting lug t to which is bolted s lever .l5 hy which the heed may he turned to any desired angle and then securely locked by the stop serew J, As shown, the cross-slide D1 is operated hy ineens ol s screw K running transversely oi the mrriuge; said screw being journsled :it l appurtenunt to or integr-nl with esrrisge brise D, moving the cross-slide D* through the medium of nut K2 integral with said Pross-slide The Pross-[eed serew K is provided at its forward extremity with the Crank K3 seeured thereto, Whiffh may he operated` whenever desirahle to nieve the cross-feed.

The swingingT head .T Carries two vertical standards li, that terminate in journal boxes L, carrying the eutter head spindle L2 that is provided with o pulley L sind preferably driven by an over heed drum, not shown. Serured to one end of the spindle L2 is a cutA
